Step-by-step explanation:

We are asked to solve the following equation for y.

To solve for y, we have to isolate the variable by performing the inverse operations.  First, move all the terms without a variable or the constants to one side, and the terms with a variable to the other side.

4.2 is being subtracted and the inverse operation of subtraction is addition. Add 4.2 to both sides.

3y is being added and the inverse operation of addition is subtraction. Subtract 3y from both sides.

y is being multiplied by -5. The inverse operation of multiplication is division. Divide both sides by -5.

Check the answer by substituting -1.2 back into the original equation.

This checks out, so we know our answer is correct.
